Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the component matches the specific pin configuration for the S-1121 series, which differs from the S-1111 series. Confirm the environmental code indicates lead-free and halogen-free compliance if required by design specifications. Ensure the ordering suffix corresponds to the correct tape and reel packaging format.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this part when a fixed 3.8 V output is required with high accuracy. Consider the package power dissipation limits when designing for high output currents. Verify that the external output capacitor meets the ESR requirements for stable phase compensation to prevent oscillation during operation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the S-1111/1121 Series of high ripple-rejection low dropout CMOS voltage regulators. The S-1121 variant is distinguished by its specific pinout arrangement compared to the S-1111 series. Both series share similar electrical characteristics but are designed for different board layout configurations.
